NXP Semiconductors NFC CARD has developed NTAG203 - NFC Forum Type 2 Tag compliant IC – to be used with NFC enabled devices according to NFC Forum technical specifications , according to NFC Forum recommendations or Proximity Coupling Devices (PCD), according to ISO/IEC 14443A . The communication layer (RF Interface) complies to parts 2 and 3 of the ISO/IEC 14443A standard. The NTAG203 is primarily designed for NFC Forum Type 2 Tag applications (i.e. Smart Advertisement, connection handover, Bluetooth simple pairing, WiFi Protected set-up, call request, SMS, goods and device authentication and others).
Features and benefits
RF Interface (ISO/IEC 14443A)

>168 bytes of total memory, divided in 42 pages (4 bytes each)
> 144 bytes of user r/w memory area, divided in 36 pages (4 bytes each)
> Field programmable read-only locking function per page for first 64 bytes
> Field programmable read-only locking function per block
> 32-bit user definable One-Time Programmable (OTP) area
> 16-bit counter
> Data retention of 5 years
> Write endurance 10000 cycles
> Anti-cloning support by unique 7-byte serial number for each device
> 32-bit user programmable OTP area
> Field programmable read-only locking function per page for first 512 bits
> Read-only locking per block for rest of memory combo cards
The anticollision function is based on an rfid inlayindividual serial number called Unique IDentifier. The UID of the NTAG203 is 7 bytes long and supports cascade level 2 according to ISO/IEC 14443-3.
An intelligent anticollision function according to ISO/IEC 14443 allows to operate more than one card in the field simultaneously. The anticollision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is performed correctly without data corruption resulting from other cards in the field.
The two have combo cards NFC function equipment link, realize point-to-point data transmission. Based on the model. Multiple which has the function of N FC digital cameras, PDA, computer, mobile phone can be wirelessly to realize data exchange between subsequent associated application is the local application can also be a web application. Typical applications of the model are to assist quickly establish a bluetooth connection, exchange, mobile phone card and data communication, etc.
